IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 167,017, dated August24, 1875; application filed July 28, 1875.

To all whom it may concern Be it known that I, JULIUS A. PEASE, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Lamp-Burners; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawing, and to the letters of reference marked there on,which form a part of this specification, in which Figure 1 is a sideview of the tube, collar, I

and cap, Fig. 2, a vertical side section through the line a: 00 of Fig.3, and Fig. 3 a vertical transverse section through the line 3 y of Fig.2; and Fig. 4, a top view of the removable cap.

My invention relates to that kind of lamps which are used to burnpar-affine, lard, tallow, and the cheap oils; and it consists in amovable cap for the lamp, provided with airducts, which direct currentsof air to .the flame, for the purpose of spreading the same andproducing perfect combustion, and also in the combination of the saidcap with a tube for conducting heat to the. material in the bowl of thelamp, the said tube being partitioned near its top to form a reservoir.

In the drawing, -A represents a collar, which is connected by anysuitable means to the mouth of the lamp. B is a tube, which extends intothe lainps bowl or chamber, and is to conduct heat to the parafline,lard, tallow, or like material in said chamber, for the purpose ofmelting the same. It has, at or near its top, screw-threads, and isfastened to the lamp by screwing into the above-mentioned collar. Apartition is placed transversely in the tube B, near its top, to .form areservoir, 0, for the reception of paraffine or like material, which isto supply the wick until the paraffine or heavy oil in the lamps bowl'orchamber can be melted. The wick-tube D rises through the partition intube B, and at the point a has slots for the ordinary ratchet used toraise the wick, and for the passage of oil to the wick. E is the cap forthe lamp, and is made with. air-ducts e. The ducts are to directcurrents of air to both sides of the lard, tallow, or like material isput into the lamps bowl or chamber, either in a melted or solid state,and the tube B screwed into the collar A. The reservoir (J is partiallyfilled with oil, usually the same as that in the lamps chamber. The capE is placed in position,

and the wick lighted. The cap soon becomes heated, and conducts the heatto the tube B, which heats and melts the oil in reservoir 0. The wick,being supplied with oil from reservoir 0 through slots in the tube D,continues to burn, and the heat transmitted to tube B gradually extendsthe length of the tube, and melts the paraffine or like substance in thelamps chamber, which is thus put in fit condition to supply the wickjust as soon as all the oil in reservoir 0 has been used.

This present invention is an improvement on the patent granted meOctober 28,1873, numbered 144,130.

1 am aware that in kerosene-lamps the wicktube has been made withair-ducts on both sides of it; but such is not my invention.

Having described my invention, what I claim is 1. In combination withthe removable cap E, provided with flameorifice, the air-ducts 6,attached to the sides thereof, and adapted to conduct air to the sidesof the flame, substantially as set forth.

2. The detachable cap E, provided with airducts c, in combination withthe tube B, reservoir G, and wick tube D, substantially as and for thepurpose set forth.

In testimony that I claim the foregoing as my own I have affixed mysignature in presence of two witnesses.
